Noise from stack
We are having a problem with foghorn and tooting coming from our stack. It originally started as a foghorn blast after toilet flush. Now it is a series of tooting sounds when ANY water is used from any sink, washer, shower, etc. Mind you, it is not making noise while water is in use. The noise begins upon turning off the flow of water. Any suggestions would be appreciated a this is driving me nuts!

A long time ago I had a call with symptoms like yours, Only this one kicked in at 3 in the AM and scared hell out of the customers. They thought their house was haunted. They were about to move out. It was hard the track down because the water picked up the vibration and carried it throughout the house. We call that sympathetic viberation. Remove the lid and check the water level. The water level should be 1/2" below the top of the white overflow tube when the tank is filled. Take your hand and run it around the flat part of the flapper. Are the edges a little wavey? If so you have found the culprit. What's happening is the water seeping past the flapper lowers the water level in the tank and the ballcock attempts to compensate. In time the water seeping out and the water coming in will balance out. The ballcock can't shut off and the sound you hear is the washer vibrating against its seat. The repair is simple. Replace the flapper. A few installation tips. The linkage between the flapper and the flush lever should have 1/4" of play when the flapper's seated. Hope this helps, Tom
